ATTACHMENT FOR HYDRAULIC WHEEL-PRESSES.

Specification of Letters Patent.

Patented Mar. 1, 1910.

Application filed January 27, 1909. Serial No. 474,413.

To all whom fit may concern:

Be it known that l, MARTIN MioirAnL MouaN, a citizen ot' the United States, residing at Ogden, in the county o1 lVeber and State of Utah, have invented certain new and useful Improvements in Attach ments for Hydraulic lVheel-Presses, of which the following is a specification, re'lerence being had therein to the accompanying drawing.

This invention relates to hyd 'aulic presses especially adapted for removing car wheels from their axles, and has in view certain improvements in such presses whereby it is possible to remove both wheels from an axle at practically the same time and thereby obviate the laborious task of turning the axle end for end such as is necessary when but one wheel is removed at a time.

In carrying out the general object of the invention stated above it is contemplated employing a rest for the axle so that the wheels on each end thereof will be in a po sitio/n to be pushed from the ends ot' the axle by means oi' oppositely moving rams which are operated by means ot hydraulic pressure forced into their cylinders by a pump, intermediate valve mechanism being employed for regulating or controlling the pressure exerted upon the rains so that various degrees ot' pressure may be exerted thereupon to compensate for the amount of force that may be required when one wheel tits the axle tighter than the other.

In the practical application of the invention for the purpose primarily intended, it will, otl course, be readily understood that various changes in details and structural arrangements may be resort-ed to, one practical embodiment of which is shown in the accompanying drawings, wherein-- Figure l is a side elevation of a wheel remover, showing the practical application of the same. Fig. 2 is a detail sectional View of a portion of the cylinders of the machine and the valve controlled communication therewith. Fig. 3 is a bottom plan view ol the valve casing detached from the main cylinder, the valves or plugs therein being indicated by dotted lines. Fig. et is a bottom plan view of the pump casing. Fig. 5 is an end View of the pressing-ott cylinders, showing the connection between the rams therein.

Referring to the accompanying drawings by numerals, the press or machine comprises in its general organization, two spaced apart beams or supports 1 which have one otI their ends connected by means o'l a strong truss beam 2 which may have formed integral with its central portion a main cylinder 3 which extends transversely o't' said beam 2 and carries a ram 4 the -front, end of which projects beyond the front end ot said cylinder and is provided with an annular flange 5 Ytroni which projects a tapering sleeve 6 which has a threaded engagement with a sleeve 7 upon which the wheels are received when forced ottl their axle, said sleeve 7 being provided with an annular llange 8 which acts as an abutment ior the hub of thc wheel to limit its movement on said sleeve. The tapering sleeve (3 is provided with an outstanding eye 9 which has a rod connection 10 with one 01 the side beams 1 to assist in holding the same stationary and imparting strength thereto when the ma chine is in use.

The ends of the beam 2 may be bifurcated to engage over the side beams 1, as will be described in detail later on in connection with one ol the other figures of the drawing in which the same connection is shown in section. The other ends oi the side beams 1 are similarly connected by means ot' a truss beam 11 provided with a central transversely arranged recess or seat 1Q the inner end of which is provided with an annular v[lange 13 carrying an eye 1-1 which has a rod connection 15 with one of the side beams 1. An abutment shoulder 16 projects' from the an nular flange 13, and said abutment shoulder 1G carries a laterally projecting rod or tube 17 upon which a wheel is received when pressed or pushed l'rom its axle, the abutment shoulder thereon serving as a stop to limit the movement oit the wheel thereon. The beam 11 may be moved longitudinally oit the side beams 1, for a purpose to be set forth later on.

An axle rest extends across the intermediate portion of the space between the side beams 1, said axle rest being ot heavy metal and having its ends biturcated, as indicated at 1S in Fig. 5 o1 the drawings, the bifurcated members of the ends being provided with slots 19 which are engaged by pins 20 passing transversely through the side beams 1 for holding said ends in engagement with the side beams. The axle rest is provided with two transversely arranged cylinders 21--22, which are spaced apart, but connected by means of a concaved transversely arranged axle seat 23 which is suitably 'reinforced to withstand the weightto which it is subjected. Each cylinder is centrally divided by means of a partition plate 24 to divide the same into two pressure chambers 25)*26 which have independent communication with a source of power. A pressing-off ram 27 is mounted for reciprocation in each cylinder, the end of which that projects beyond theV cylinders having a yoke connection 28 with the ram in the cylinder on the opposite side of the axle rest or seat 23. Said yoke has a centrally concaved portion 29 corresponding with the concavity of the axle seat 23. As aforesaid, each cylinder or pressure chamber has a separate communication with a source of hydraulic pressure supply, such communication consisting` of a threaded opening 30 into which is threaded a pipe 3l which connects with a supply pipe 32 in communication with a valve chamber 33 which has an annular iange 34? adapted for secure and rigid attachment to the main cylinder 3. Said valve chamber 33 has two straight passages 35 therethrough which communicate with the supply pipes 32 at one end, and at their other end have a pipe connection 36 with a pump or pumps 37, having a suitable connection with a source of water supply. The two straight passages 35 are intersected by a main cylinder supply passage 3S, turning plugs being interposed at the point of intersection of the straight passages 35 and the main cylinder supply passage 38, said plugs being designated by the numeral 39 and being provided with three-way passages whereby the pressure supply from the pump 37 may be diverted into the main cylinder 3, or permitted to pass through the supply pipes 32 and thence to the cylinders or pressure chambers 25 and 26, as is shown in detail in Fig. 2 of t-he accompanying drawings. A drain passage i0 connects the straight passages 35, said drain passage being provided with a two-way plug Lll to permit the water to be drawn from the cylinders 25-26- The beam ll is slidably mounted in the bars l and may be locked thereto by means of the wedges lla. As shown in F ig. l said beam is in the position to coperate in the pressing-off of the wheels B.

ln using the invention, the wheel axle A is placed within the axle seat 23 with the outstanding portion 29a of the yokes 29 bearing against the inner face of the hubs of the wheels B. The plugs or valves 39 are turned to open communication through the valve i chamber 33 from the pump 37 to force the hydraulic pressure through the pipes 32 and into the chambers 25-26 and cause the rams 27 to force the yoke 29 against the wheel with sufficient Vforce to remove the wheels from the axle and onto the sleeves 7 and '17 of the beams 2 and ll. By this means, both wheels are practically removed simultaneously, thereby avoiding the necessity of turning the axle end for end, such as is necessary when but one wheel is removed at a time. Y

While in the foregoing particular stress has been laid on the value of the invention for removing wheels from axles, the same is also capable of placing wheels thereon, this operation being performed by the main cylinder 3, its cooperating ram 4t, the beam ll and the rams adjacent thereto. To place the wheel on the main cylinder end of the axle, the sleeve 7 is removed from the tapering sleeve 9 of the ram el, and while the axle is held in the axle seat 23 the wheel is brought to position so that the opening through its hub will register with the axle and the beam sleeve 2 abuts against the hub of the wheel, whereupon pressure is admitted to the cylinder through manipulations of the turningplugs 39, and the ram 4 will force said wheel onto the axle. To place a wheel o-n the other end of the axle, said axle is held in the axle rest l2 of the beam l1. The wheel to be pressed onto the axle is held with its hub in contact with rams 28, and said beam is then moved horizontally of the bars l to bring the end of the axle and the opening of said hub in contact, whereupon, when pressure is applied to the cylinders 26, the rams thereof will press the wheel onto the end of the axle.

It will be seen from the foregoing that the invention is one that can be readily operated to perform the functions for which it is designed by simply manipulating the turning plugs to send the pressure from the pump to the cylinders that are to be used for removing or replacing the wheels, thereby greatly economizing in labor. It will also be understood that the pump and valve chamber shown and described are but one of the many types of such that may be used and therefore it is to be understood that the invention is in no wise to be limited to the described construction of pump and valve or chamber.
